无论是602还是801都是用专门的USB音频接收芯片接收USB音频信号转为I2S信号再送入自带的PCM1704U-K或者TDA1543独立解码。headfonia的测评人认为602做USB声卡的音质要比801的USB声卡要好。实际上602的USB输入部分的设计的确相对于801做了改进。
参见如下英文测评
http://www.headfonia.com/hifi-da ... -qa350-boomslang/3/
* Hifiman 801 DAP = Detail, ambience, bass, depth, separation
* Ibasso DB1+PB1 Coax = Soundstage slightly more narrow than HRT, but more refined, little details, depth, separation
* HM602 DAP = Soundstage slightly more narrow than Ibasso DB1+PB1 Coax, but still very good micro details, depth, separation better than HRT2
* HRT MS2+ USB = Very good overall. Widest soundstage (even wider than HM801), but micro details, depth, separation is not as good as the three above it.
* HM602 USB DAC = slight downgrade than the DAP version, loses a little bit of refinement.
* Ibasso DB1+PB1 USB = also downgraded, and more than the HM602 this time
* QLS QA350 = wide soundstage, good separation, but lacks depth and micro details
* HM801 USB DAC = soundstage and detail suffers a lot, but still maintains separation and depth.
(Least)
Frankly I’m impressed with two things. First is the quality of the HM-801 source. Though it was no.1 in my last DAP comparison, I was comparing it with “mainstream” products. This time the competition is much tougher, and yet the HM-801 maintains quite a big gap in sonic performance to the second in line: the DB1+PB1. I really would consider using the HM-801 as a desktop source, perhaps as an office rig, as you practically don’t need any other amp for most headphones. The second thing that impresses me is how the newer, smaller, lighter, and cheaper HM-602 DAP gives such a good performance in the midst of all the other players. From a practical standpoint, I don’t think it gets any better than the HM-602. The thing is lighter than my Ipod Classic, and yet it gives an outstanding sound quality with a signature that’s even more likeable than the bigger brother.
Other than that, I think the Ibasso concept is quite interesting, but I probably be sticking to just the Toucan amp and skipping the Boomslang DAC, as three packs are just too much for me.
